Loss of Appetite A sudden refusal to eat or drink can indicate stomach pain. Cats may avoid food because eating worsens their discomfort.
Vomiting Occasional hairball-related vomiting is normal, but frequent vomiting, especially with bile or undigested food, could signal an upset stomach.
Diarrhea or Constipation Loose stools, frequent bathroom trips, or difficulty passing stool are signs of digestive trouble. Watch for changes in litter box habits.
Excessive Licking of the Belly Cats may over-groom their abdominal area when experiencing pain, leading to bald patches or skin irritation.
Lethargy and Weakness A cat with a stomach ache may be less active, sleep more, and show little interest in playtime.
Hunched Posture If your cat sits or walks with a hunched back and appears tense, it might be trying to ease stomach discomfort.
Unusual Meowing or Irritability Cats in pain may become more vocal, restless, or even aggressive when touched around the belly.
